In an sinister old library, presided over by the portrait of a grim-faced, mad eyed old man, a dusty lawyer reads a will to an equally sinister family - one member of which has werewolf tendencies, another wanders around in a toga, a third is a gentle elderly lady who plants more in than seeds in her flowerbeds. By the third act there are more corpses than live members left in the cast.

A crusty old lawyer and his secretary gather the remaining Tomb family at the old house to inform them of their inheritances. But the lawyer would like the inheritance for himself. Fog descends on the mansion, and in the cobwebby corridors things - and people - are seldom what they seem. With poison in every decanter and disappearances into secret passageways, host and guests alike join the increasing number of bodies in the cellars.

​Monument House Hotel and Alternative Health Spa receives a series of unexpected guests. The uninvited guests are soon snooping around the secret passages of the old mansion and asking too many questions. one by one they fall victim to death by devious techniques - no secret panel is unoccupied, no cup of tea untouched, and nobody is who they appear to be.​

"Where there's a will - there's relations" or so they say in Yorkshire. But when everyone has a will naming them as sole heirs, who will inherit. As they all reel in shock the first 'accident' occurs prompting a cunning plan for others to get their hands on the cash, but as they conspire, a ruthless killer stalks the house and bodies fall like flies. Whodunit? Alcoholic Miriam, venomous Velma, dreadful Donna, male stripper Troy or Mummy's boy Fordyce?
